Question

我试图让一个按钮为语言学习应用程序播放声音..因此，当用户点击按钮时，它会说出＆＃34;你好吗＆＃34;

无论如何，我得到错误＆＃34;无法解决方法＆＃34; on（Tab1Fragment.this，R.raw.howareyou）; ，setContentView和findViewById

这是我的代码..

Tab1Fragment.java

package com.storey.user.storeytom.fragments;

import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.View;
import android.widget.Button;
import com.demo.slidingmenu_tabhostviewpager.R;

public class Tab1Fragment extends Fragment {

    @Override
    public View onCreateView(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
        setContentView(R.layout.tab1fragment);

        final MediaPlayer buttonSound = MediaPlayer.create(Tab1Fragment.this, R.raw.howareyou);
        Button btn1 = (Button) findViewById(R.id.button);
        btn1.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
            buttonSound.start();
            startActivity(new Intent("com.storey.user.storeytom"));}
        });

这里是我的.xml文件，如果你还需要...

tab1fragment.xml

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:text="Conversation" />

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="btn1"
            android:id="@+id/button"
            android:layout_gravity="center_horizontal" />


    </LinearLayout>

抱歉＆＃34; nooby＆＃34;问题...提前谢谢

Answer 1

final MediaPlayer mp = MediaPlayer.create(getActivity(), R.raw.sound));

    Button play_button = (Button)this.findViewById(R.id.button);
    play_button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Log.v(TAG, "Playing sound...");
            mp.start();
        }
    });

或者检查一下：android - how to make a button click play a sound file every time it been pressed?
